Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill failed 1 of 6 checks. A failure is not proof of bad intent; it means something in the code needs a human to look at it before you run it.

  • No undeclared network calls: failed

    Contacts 1 host that is neither well-known infrastructure nor declared in the skill's frontmatter: openoffice.org.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

About this skill

What it does

This skill allows AI agents to process and extract data from .xlsx (Microsoft Excel) files. It can read data from spreadsheets, interpret cell values, and potentially perform calculations based on the spreadsheet content. The agent can then use this extracted information for further tasks or analysis.

When to use it

  • Data Extraction: Automatically pull specific data points from a financial report in .xlsx format.
  • Inventory Management: Read inventory levels from an Excel sheet and update a database accordingly.
  • Report Generation: Use spreadsheet data as the basis for generating summaries or reports.
  • Budget Analysis: Analyze budget spreadsheets to identify spending trends and potential areas of concern.

Key capabilities

  • Reads .xlsx files
  • Extracts data from cells within spreadsheets
  • Interprets cell values (numbers, text, dates)

Example prompts

  • "Read the 'Sales Data' spreadsheet and tell me the total sales for Q3."
  • "Extract all customer names and email addresses from the 'Customer List.xlsx' file."
  • "What is the average price per unit in the 'Product Pricing.xlsx' sheet?"

Tips & gotchas

  • The skill requires access to the .xlsx file, either locally or via a URL.
  • Complex formulas within the spreadsheet may not be fully interpreted; focus on simple data extraction for best results.
